红帽全球峰会8.6. 手动更新安装的操作系统
要手动从注册中心获取更新，并将系统引导至新更新，请使用 bootc upgrade。该命令将事务性就地更新从已安装的操作系统获取到容器镜像注册中心。命令查询注册中心，并为下一次启动将更新的容器镜像排队。它暂存对基础镜像的更改，而不是默认更改正在运行的系统。
流程
运行以下命令:
bootc upgrade [--apply]
$ bootc upgrade [--apply]Copy to Clipboard Copied! Toggle word wrap Toggle overflow apply参数是可选的，当要自动执行操作时，您可以使用它，比如系统更改后的重启。
注意
bootc upgrade 和 bootc update 命令是别名。
